HERNIAL TRUSS Filed Oct. 25. 1929 Z'snnentor AUGUST SGHAFFER M (IttornegPatented Sept. 13, 1932 UNITED STATES HERNIAL muss }-f ApplicationfiledOctober 25, 1929; 1. Serial 110,402,525."

This invention relates to trusses for ruptures, especially thoseinvolving a protrusion of the intestine, and the object of the inventionis to provide an improved construction whereby the truss is moresecurely supported in its place, and without the necessity of a legstrap especially for persons of sedentary habits and who do no heavylifting. Other objects will appear from the disclosure herein.

The invention is embodied in the example herein shown, the features ofnovelty being finally claimed.

In the accompanying drawing- Figure 1 is a front view of the deviceaccording to the invention.

Fig. 2 is a view of the pad member looking at the lower edge of thatmember as seen in Fig. 1.

Fig. 8 is a vertical section on the line III- III Fig. 1.

Fig. at is a view of the rear face of the pad proper removed from theframe plate.

Inthe views 5 designates the frame which is a thin metallic plate uponwhich is riveted a rather hard rubber foundation 6. The lower portion ofthe plate 5 is bent rearward where it is built up with pieces of leather7 or other suitable material to afford a supporting face that iscompoundly curved as best I seen at 7 Fig. 2. Upon the surface 7 issecured a pad 8 called a supplemental pad of sponge rubber the curve ofthe lower edge of which conforms to the curve of the supporting face 7,said edge projecting slightly below the edge of the supporting face andconforming to the pubic portion of the pelvic bone.

The frame near its central portion is provided with a vertical slot 9through which is inserted from the front side a screw 10 or pin-likemember adapted to engage at its inner end a button 11; and on said screw10 is a washer 12 sliding with said screw. Between said button and thewasher 12 is a coil spring 13 tending to hold the buttonll pressed andprojecting rearward toward the body of the washer. The screw 10 with itssaid appurtenances is movable up and down in the slot 9; and said partsalso may have a slight universalmmovement This capacity. of the screwfacilitates the application and removal of the pad proper which will nowb'e'de scribed; Y

The character 14 designates said pad, it being preferably made of spongerubber. Said pad is provided at its forward side with a central socket15 so that it can be sprung onto the button, or removed therefrom, atwill and be placed in substantially the position in Fig. 3. The upperportion of the pad, at its forward side, is made with an arcuate recess16 around the socket and spaced therefrom so as to make that portion ofthe pad somewhat more yielding than otherwise to pressure.

' The pad 8 can be called the supplemental or supporting pad because itis designed to prevent downward displacement of the truss, its loweredge being designed to conform generally to the upper surface of thepubic portion of the pelvic bone while the pad proper 15 operates tohold the intestine up. Because, in use, the pad 8 is lodged above thepubic bone the truss is held from descending from its proper place.

To hold the pad to the body after its adjustment thereto and to draw thelower pad inward over the pubic bone the plate 5 is provided withlateral hooks 17 set at an incline to the plate to which the oppositeends 5 18 of a body strap are attached as shown in F ig. 1. Said bodystrap is provided with the usual buckles for holding it as tight asnecessary to keep the pad in proper position.

If the patient does heavy lifting one end of a leg strap can be attachedto a pin 20 on the plate 5 and pinned or otherwise secured to the rearof the body strap.

The truss shown is for a rupture at the right hand side. For the lefthand side the curve of the supporting pad 8 is merely the reverse ofthat shown so as to fit above the pubic bone at the left hand side.Otherwise the parts can be identical but the forms of the parts can bechanged without departing from the gist of the invention as claimed.

What I ilaim is:

1. A hernial truss including a plate having an inwardly bent anddownwardly inclined lower portion, a pad proper yieldingly ()f BEIGE?ion and slidingly supported for vertical movement on the upper portionof said plate; and a supplemental pad rigidly supported on the lowerbent portion of said plate said pad being horizontally elongated to restabove and be supported by the pubic bone of the wearer.

2. A hernial truss includinga plate having an inwardly bent anddownwardly inclined lower portion, a pad proper yieldingly and slidinglysupported for vertical movement on the upper portion of said plate; anda slipplemental pad rigidly supported on the lower bent portion o'f saidplate, said pad being i horizontally elongated and having its bear ingface inclined downwardly toward the body of the wearer, and'adapted torest above, and be supported by, the pubic bone of the wearer. 1
